Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I'm not so sure about that.... you'll have water, electric and wastewater all in place... and in most cases a sound foundation with some clean up.
We demoilshed and rebuilt in 2011/2012 and our demolition costs were only $7k and permit was $25 but we are out in the boondocks.
This is one of those YMMV (as are MOST things in life, right?) I saw many accounts of folks in California that were smacked in the face with the amount of money that was required to "start over" when they lost their homes to wildfires. Some folks luck out in that it could be cheap or get screwed when it's much more than they anticipated.
In our case, we have a well, septic and plumbing under the slab. None of that would be easy to just "hook back up."
